First among these is the physical factor which conditions human activity but is not a compelling force, for man has often subdued his environment when it has put obstacles in his way. This physical element includes the geographical conditions of mountain, valley, or seashore, the climate and the weather, the food and water supply, the physical inheritance of the individual and the laws that control physical development, and the physical constitution of the group. A second factor is the psychic nature of human beings and the psychical interaction that goes on between individuals within the group and that produces reactions between groups.
359. The Natural Environment.—The early sociologists put the emphasis on the physical more than the psychic factors, and especially on biological analogies in society. It seemed to them as if it was nature that brought men together. Mountains and ice-bound regions were inhospitable, impassable rivers and trackless forests limited the range of animals and men, violent storms and temperature changes made men afraid. Avoiding these dangers and seeking a food-supply where it was most plentiful, human beings met in the favored localities and learned by experience the principles of association. Everywhere man is still in contact with physical forces. He has not yet learned to get along without the products of the earth, extracting food-supplies from the soil, gathering the fruits that nature provides, and mining the useful and precious metals. The city-dweller seems less dependent on nature than is the farmer, but the urban citizen relies on steam and electricity to turn the wheels of industry and transportation, depends on coal and gas for heat and light, and uses winter's harvest of ice to relieve the oppressive heat of summer. Rivers and seas are highways of his commerce. Everywhere man seems hedged about by physical forces and physical laws.
Yet with the prerogative of civilization he has become master rather than servant of nature. He has improved wild fruits and vegetables by cultivation, he has domesticated wild animals, he has harnessed the water of the streams and the winds of heaven. He has tunnelled the mountains, bridged the rivers, and laid his cables beneath the ocean. He has learned to ride over land and sea and even to skim along the currents of the air. He has been able to discover the chemical elements that permeate matter and the nature and laws of physical forces. By numerous inventions he has made use of the materials and powers of nature. The physical universe is a challenge to human wits, a stimulus to thought and activity that shall result in the wonderful achievements of civilization.
360. The Human Physique.—Another element that enters into every calculation of success or failure in human life is the physical constitution of the individual and the group. The individual's physique makes a great difference in his comfort and activity. The corpulent person finds it difficult to get about with ease, the cripple finds himself debarred from certain occupations, the person with weak lungs must shun certain climates and as far as possible must avoid indoor pursuits. By their power of ingenuity or by sheer force of will men have been able to overcome physical limitations, but it is necessary to reckon with those limitations, and they are always a handicap. The physical endowment of a race has been a deciding factor in certain times of crisis. The physical prowess of the Anakim kept back the timid Israelites from their intended conquest of Canaan until a more hardy generation had arisen among the invaders; the sturdy Germans won the lands of the Roman Empire in the West from the degenerate provincials; powerful vikings swept the Western seas and struck such terror into the peaceful Saxons that they cried out: "From the fury of the Northmen, good Lord, deliver us."
361. Biological Analogies.—The physical factor in society received emphasis the more because society itself was thought of as an organism resembling physical organisms and dependent upon similar laws. As a man's physical frame was essential to his activity and limited his energies, so the visible structure of social organization was deemed more important than social activity and function. Particularly did the method of evolution that had become so famous in biology appeal to students of sociology as the only satisfactory explanation of social change. The study of animal evolution made it clear that heredity and environment played a large part in the development of animal life, and Darwin pointed out that progress came by the elimination of those individuals and species least fitted to survive in the struggle for existence and the perpetuation of those that best adapted themselves to environment. It was easy to find social analogies and to reach the conclusion that in the same way individuals and groups were creatures of heredity and environment, and the all-important task of society was to conform itself to environment. Of course, history disproved the universality of such a law, for more than once a race has risen above its environment or altered it, but it seemed a satisfactory working principle.
Biological analogies, however, were overemphasized. It was a gain to know the workings of race traits and the relation of the individual to his ancestry, but to excuse crime on the ground of racial degeneracy or to despise a race and believe that none of its members can excel because it is conspicuous for certain race weaknesses has been unfortunate. Similarly there was advantage in remembering that environment is either a great help or a great hindrance to social progress, but it would be a social calamity to believe in a physical determinism that leaves to human beings no choice as to their manner of life. The important truth to keep in mind is that man and environment must be adapted to each other, but it often proves better to adapt environment to man than to force man into conformity to environment. It is the growing independence of environment through his own intellectual powers that has given to civilized man his ascendancy in the world. It is a mistake, also, to think that a struggle for existence is the only means of survival. As in the animal world, there comes a time in the process of evolution when the struggle for selfish existence becomes subordinated to effort to preserve the life of the young or to help the group by the sacrifice of the individual self, so in society it is reasonable to believe that the selfish struggle of individuals will give way by degrees to purposeful effort for social welfare, and that the solidarity of the group rather than the interest of the individual will seem the highest good. Then the group will care for the weak, and all will gain from the strength and prosperity of the whole.
362. The Importance of the Individual.—While it is true that individual interests are bound up with the prosperity of the group, and that the food that he eats, the clothes that he wears, and the money that he handles and uses are all his because social industry prevails, there is some danger of overlooking the importance of the individual. Though he does not exist alone, the individual with his distinctive personality is the unit of society. Without individuals there would be no society, without the action of the individual mind there would be no action of the social mind, without individual leadership there would be little order or progress. The single cell that made up the lowest forms of animal life is still the unit of that complex thing that we call the human body, and the well-being of the single cell is essential to the health and even the existence of the whole body; so the single human being is fundamental to the existence and health of the social body. No analysis of society is at all complete that does not include a study of the individual man.
363. The Psychology of the Individual.—Self-examination during the course of a single day helps to explain the life forces that act upon other individuals now and that have forged human history. In such study of self it soon becomes apparent to the student that the physical factor is subordinate to the psychic, but that they are connected. As soon as he wakes in the morning his mental processes are at work. Something has called back his consciousness from sleep. The light shining in at his window, the bell calling him to meet the day's schedule, the odor of food cooking in the kitchen, are physical stimuli calling out the response of his sense-perceptions; his mind begins at once to associate these impressions and to react upon his will until he gets out of bed and proceeds to prepare himself for the day. These processes of sensation, association, and volition constitute the simple basis of individual life upon which the complex structure of an active personality is built.
The individual will is moved to activity by many agencies. There is first the instinct. As a person inherits physical traits from his ancestors, so he gets certain mental traits. The demand for food is the cry of the instinct for self-preservation. The grimace of the infant in response to the mother's smile is an expression of the instinct for imitation. The reaching out of its hand to grasp the sunshine is in obedience to the instinct for acquisition. All human association is due primarily to the instinct for sociability. These instincts are inborn. They cannot be eradicated, but they can be modified and controlled.
Obedience to these native instincts produces fixed habits. These are not native but acquired, and so are not transmitted to posterity, in the belief of most scientists, but they are powerful factors in individual conduct. The individual early in the morning is hungry, and the appetite for food recurs at intervals through the day; it becomes a habit to go at certain hours where he may obtain satisfaction. So it is with many activities throughout the day.
